Abstract

PURPOSE:To accurately ignite a plurality of sparklers simultaneously or at a predetermined time interval by securing an electric igniter for enclosing an electric bridge bridged between the ends of a pair of leads with igniting wire to the end of a powder unit. CONSTITUTION:An electric igniter 1 has an electric bridge 3 made of a platinum wire, etc., bridged between the ends of a pair of leads 2 and 2' and enclosed with an ignition ball 4. An adhesive tape 8 is secured, for example to the end of a powder unit 6 in a state that the igniter 1 is brought into contact with the end of the power unit 6 via the ball 4. This sparkler momentarily generates heat at the bridge 3 when the igniter 1 is energized, and the ball 4 is burned. Accordingly, a plurality or many sparklers are arranged, for example, to express specific design, picture, character, etc., and can be accurately ignited simultaneously or at a predetermined time interval by a remote operation.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a sparkler, which is a type of firework.

[Conventional technology]

Sparklers that have gunpowder fixed to their shafts have traditionally been used.

(Problems to be Solved by the Invention) Sparklers are generally ignited by a candle flame, etc., but in many cases, the candle flame does not easily ignite. Therefore, sparklers with ignition powder fixed to the tip of the gunpowder part are also sold.

However, even sparklers in which ignition powder is fixed to the tip of the explosive part may not necessarily ignite easily.

Further, regardless of the presence or absence of ignition powder, it is difficult to accurately ignite a plurality of sparklers at the same time or at regular intervals, even if a fuse or the like is used.

The present invention has been made in an attempt to solve the following problems.

[Means to solve the problem]

In order to solve the above problems, the present invention provides the following sparkler equipped with an electric ignition device.

1. An electric ignition device consisting of an electric bridge spanning the tips of a pair of conductive wires and surrounding the electric bridge with an ignition ball is placed at the tip of the gunpowder section with the ignition ball in contact with the tip of the gunpowder section. 2. The sparkler is characterized in that the electric igniter is fixed to the tip of the explosive part in a state where the ignition ball is in contact with the ignition powder fixed to the tip of the explosive part. Sparkler 3, fixing black powder or thermite gunpowder on the ignition powder at the tip of the gunpowder part, and fixing the electric ignition device to the tip of the gunpowder part with the ignition ball in contact with the black powder or thermite gunpowder. 4. A mixture of ignition powder and black gunpowder or thermite gunpowder is fixed to the tip of the explosive part, and the electric ignition device is connected to the explosive part with the ignition ball in contact with the mixture. 5. The electric ignition device is attached to the tip of the explosive part through a cylinder, and the space between the electric ignition device and the tip of the explosive part in the cylinder. The sparkler 6 is characterized in that the electric ignition device is attached to the tip of the explosive portion to which the ignition powder is fixed via a cylinder, and the electric ignition device and the ignition device in the cylinder are attached. In the sparkler of the present invention, when the electric ignition device is energized, the electric bridge instantaneously generates heat and the ignition ball burns. . Itoshi, the sparkler of each claim burns in the following order.

*Sparkler of claim 1 - Ignition ball → Gunpowder part * Sparkler of Claim 2 - Ignition ball → Ignition powder → Gunpowder part * Sparkler of Claim 3 - Ignition ball → Black gunpowder or thermite gunpowder → Ignition mulberry → Gunpowder part * Sparkler according to claim 4 Ignition ball → mixture of explosive and black powder or thermite gunpowder → gunpowder part * Sparkler according to claim 5 Ignition ball → powder → fire mulberry part * Sparkler according to claim 6 Ignition ball → powder →Ignition mulberry→Explosive part [Example] Next, an example of the present invention will be described with reference to the accompanying drawings.

Since a similar electric ignition device 1 is commonly used in the following embodiments, this device will be explained first. An electric ignition device 1 is constructed by hooking an electric bridge 3 such as a platinum wire to the ends of a pair of conductive wires 2, 2-, and connecting the electric wires 2, 2- to the ends of the wires 2, 2-. ! 3 is surrounded by an ignition ball 4. As the igniter 4, it is preferable to use one based on rhodan lead or a diazo compound. In addition, a solvent is added and mixed.

Reference numeral 5 designates the support for the conductor 2.2'.

Note that the power source used may be, for example, a 1.5V DC power source.

*Embodiment corresponding to claim 1 (FIGS. 1 and 2) Reference numeral 6 is the explosive part of the sparkler, and 7 is the shaft. In this embodiment, the electric ignition device 1 is fixed to the tip of the explosive part 6 with an adhesive tape 8, for example, with the ignition ball 4 in contact with the tip of the explosive part 6.

*Embodiment corresponding to claim 2 (FIG. 3) In this embodiment, the electric ignition device 1 is fired with the ignition ball 4 in contact with the ignition powder 9 fixed to the tip of the explosive part 6. Part 6
For example, it is fixed to the tip with adhesive tape 8. As an example, the ignition powder 9 is mainly composed of perchlorates as an oxidizing agent, wood powder and BL combustion improver as a combustible agent, and aluminum powder, magnalium powder, titanium powder, etc. as a heat generating agent, and a starch-based powder. Use a mixture of binders. Incidentally, the ignition powder in the following examples may be the same as this.

*Embodiment corresponding to claim 3 (FIG. 4) In this embodiment, black powder or thermite-based explosive 10 is fixed on the ignition powder 9 at the tip of the explosive part 6, and the electric ignition device 1 is used to ignite it. The ball 4 is fixed to the tip of the explosive part 6 with an adhesive tape 8, for example, in a state in which it is in contact with the black powder or thermite-based explosive 10.

*Embodiment corresponding to claim 4 (FIG. 5) In this embodiment, a mixture 11 of ignition powder and black powder or thermite gunpowder is fixed to the tip of the explosive part 6, and the electric ignition device 1
is fixed to the tip of the explosive part 6 with an adhesive tape 8, for example, with the ignition ball 4 in contact with the mixture 11.

*Embodiment corresponding to claim 5 (FIG. 6) In this embodiment, the electric ignition device] is connected to the explosive part 6 through the cylinder 12.
The space between the electrical ignition device 1 and the tip of the explosive part 6 is filled with powder 13 such as black gunpowder.

*Embodiment corresponding to claim 6 (FIG. 7) In this embodiment, the electric ignition device 1 is attached via a cylinder 12 to the tip of the explosive part 6 to which the ignition charge 9 is fixed. The space between the electric ignition device 1 and the ignition powder 9 in the ignition device 12 is filled with a powder 13 such as black gunpowder.

Incidentally, the sparkler of the present invention is not limited to the linear shape shown in the drawings, but may be of any shape such as a heart shape, or may be of any shape with branches in the middle.

(Effects of the Invention) As explained above, the sparkler of the present invention accommodates the electric ignition device at the tip of the explosive part, so it ignites instantly and reliably during use. It is also possible to arrange a large number of sparklers in a pattern, such as a particular pattern, picture, letter, etc., and ignite these sparklers accurately by remote control at the same time or in sequence at regular time intervals. In this way, various ways of playing with Sparkler are possible.
